Corbyn is most popular among younger voters. Voters under the age of 25 prefer him over May by significant margins. It's those types of voters who are likely to use Tinder. By persuading younger voters to vote in Thursday's election, the Tinder bot can help boost turnout for Corbyn.

There are also some people who are using Tinder to tell people to vote for Corbyn, but without a bot.

This isn't the first time there's been a targeted social media campaign for non-United States elections. It's reminiscent of the French election earlier this year, where some people coordinated bots and fake accounts on social media to encourage people to vote for National Front candidate Marine Le Pen. They just had one problem: most of them didn't speak French.
